The top news executive at NPR announced Friday that she is leaving the organization, an unexpected departure that coincides with a shake-up in the nonprofit media giant’s management structure.

Nancy Barnes, who took over NPR’s newsroom in 2018 as editorial director of the broadcasting and digital news operation, said she will leave the organization later this fall. She did not announce new plans, but said in a note to staff on Friday that she will “pursue other journalistic endeavors.”
